Incomplete Backtest on Historical Data

[Gennaker]

Greetings NT Forum,

I imported a text file named ES 12-11.Last.txt into Ninjatrader with data going back to March of this year. I am able to see March data in edit tab of the Historical Data Manager, but when run a backtest, nothing executes earlier than 18-Jul-11 of this year. The only clue I can come up with is this is about when I started using Ninjatrader.

Thanks

...I imported a text file named ES 12-11.Last.txt into Ninjatrader with data going back to March of this year...

Of tick data? Minute data?

...when run a backtest, nothing executes earlier than 18-Jul-11 of this year...

And what do you see when you chart over the same period?

Hi Gennaker, can you please try running the same backtest with the ES master instrument set to 'DoNotMerge' in the Instrument Manager?
